Cruel fate claims the lives of former boxer Moriya and former yakuza Watase off the edge of a busy freeway overpass. But the end for these two is just the beginning. Rescued from "ground zero" by a mysterious alien woman with magical powers, Moriya and Watase find themselves trapped in a world almost like the one they left - yet completely different! Appeasing the whims of their alien overseer seems to be the only hope Moriya and Watase ever have of returning to their former lives. Will the time traveling events Moriya and Watase find themselves in bring them closer together... or will they alter the past so much, it dooms any hope for a relationship?!
